The Wacker Neuson Head Comp Cylinder is a genuine OEM component designed for CT36 and CT48 walk-behind trowel series, PT3A centrifugal trash pumps, BPS 2550A vibratory plates, MPU 29A reversible plates, and HPG50/HPG100 vibratory truss screed power sections. As a direct OEM part sourced from Wacker Neuson, the is manufactured to the same specifications as the original, ensuring it integrates correctly with the engine assembly without adaptation. This Head Comp Cylinder fits an extensive range of Wacker Neuson equipment, making it a versatile stocking part for contractors and service shops running multiple machines from this lineup. Order with confidence knowing part number has been verified against the manufacturer's parts catalog.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original casting and dimensional tolerances for the cylinder head assembly, ensuring proper combustion chamber geometry and sealing surface integrity.
- Direct Drop-In Replacement: — Matches the original mounting pattern and port configuration, allowing straightforward installation onto compatible engine assemblies with no reworking of mating components.
- Wide Fitment Coverage: — Compatible with CT36 and CT48 walk-behind trowel series, PT3A trash pumps, BPS 2550A vibratory plate, MPU 29A reversible plates, and HPG50A/HPG100A screed power sections.
- Restored Compression and Power Output: — A correctly seated cylinder head assembly maintains proper compression ratios, delivering consistent engine output so trowels finish concrete on schedule and pumps move full flow.
- Fuel System and Emissions Integrity: — The OEM head geometry preserves correct air-fuel combustion dynamics, keeping engine operation within designed emissions parameters — important for regulated jobsite environments.
The cylinder head assembly forms the upper closure of the engine's combustion chamber, housing the valves, ports, and sealing surfaces that contain and direct the combustion event. It works in conjunction with the cylinder bore and piston to generate the compression required for ignition and the power stroke that drives the machine. When a cylinder head is cracked, warped, or worn — whether through overheating, detonation, or age — compression is lost, causing hard starts, power loss, excessive fuel consumption, or engine failure. Replacing it with a genuine OEM Head Comp Cylinder restores the sealing integrity and dimensional accuracy the engine was built around.
